New data has been added to the SPRESIweb database. Users can now search over 5.8 million molecules and 4.6 million reactions abstracted from 700,000 references comprising 170,124 patents covering the years 1974 - 2014.

What's New in SPRESIweb 2.14?

01.2014

Enhanced Name Reaction Search

Version 2.0 beta of the Name Reaction search module ICNameRXN
is now released and integrated into SPRESIweb 2.14. It contains 662 name reactions and 759,000 reactions of SPRESIweb are assigned to one of these name reactions.
Please note that reaction conditions are not assigned to all records. In some cases this fact can generate false positives in the hit lists for certain Name Reaction queries.

Integration of New ICEDIT Version

The submission of structure and reaction queries has been enhanced with the integration of ICEDIT as JavaScript version (HTML5 compatible). For all browsers supporting JavaScrips/HTML5 the editor will be automatically uploaded on the fly, as the old applet was, and does not need installation of programs on the users side. At the same time, users encountering difficulties with Java versions in different browsers, will be able to define their queries further with InfoChems new and powerful drawing tool.

Update of Chemicals Suppliers Catalogs

Some of the supplier catalog information included in SPRESIweb has been updated. Users are able to identify which substances contained in hit lists are commercially available and order them right away via the hyperlink to the supplier homepage/online catalog.

What's New in SPRESIweb 2.12?

01.2013

SPRESIweb Database Refresh

SPRESIweb is by definition a web-based application that gives direct access to the complete content of the SPRESI structure and reaction database. Since 2006, all structures from the major chemical supplier catalogs were added alongside the literature structures, thus boosting the number of molecules to the 11.8 million (version 2.11). Now InfoChem has given SPRESI a major refresh and reprised the original concept of only including structures abstracted from the literature. This means that many of the small molecules and common structures that just come from catalogs have been removed. Therefore, SPRESI now only retains the catalog data and supplier links for the literature structures. The benefit of this refresh is improved content that is focused on chemistry from organic synthesis journals, whilst retaining the relevant catalog data and supplier links.

Additional Chemicals Suppliers Catalogs

The catalogs of two new chemical suppliers have been included: Apexmol and Ark Pharm. In addition, all the supplier catalog information included in SPRESIweb has been updated. Users are able to identify which substances contained in hit lists are commercially available and order them right away via the hyperlink to the supplier homepage/online catalog.

New Data

New data has been added to the SPRESIweb database. Users can now search over 5.52 million molecules and 4.26 million reactions abstracted from 675,000 references and 164,000 patents covering the years 1974 - 2011.
